Thank you, Alex. I just checked, and yes, I can see both "keycode 116 press/release" and "button/power PBTN 00000080 00000000 K" events.
I had 20.10 installed before 21.04, and I'd swear it didn't have this problem. I can reinstall 20.10 and confirm this later. Just in case it's relevant in order to confirm or discard a faulty BIOS, I also have Windows 10 installed, and this problem isn't showing there. Again, thank you for your help. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1926527 Title: "Power off" dialog appears when any three keyboard keys are pressed quickly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1926527/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
